Making Visualizations Available via WWW
- Details
Each visualization created in CoDeSys can be made available through an internet browser. The following steps are necessary:
- Right-click on the visualization object, choose “Object Properties” and make sure that the checkbox near the Web-Visualization is set.
- In the Menu Resources, choose Target Settings, there ‘Visualization’ and click the checkbox ‘Web visualization’. Additionally being there you can configure:
- Size of the visualization (Display width, Display height),
- Compression of the files uploaded to the webserver
- Enforcement of uploading the visualization files (Inhibit….)
When the above-presented steps are done you can upload the program to the PLC (‘Project’, ‘Clean all’, ‘Project’, ‘Build’, ‘Online’, ‘Login’, ‘Upload All’.
Enter in your browser the address of your PLC : http://
Although it is quite easy to build a visualization with PLC and make it available over the web, I have totally resigned from that functionality. Larger visualization composed of many control buttons were working very slow. I do not know if that was the fault of my old PC, lack of memory or a feature of the visualizations. After a few attempts of clicking and long lags I gave up.
Additionally a web visu launches a Java applet what is impossible to do in mobile phone browsers I have tested.
Finally I launch large and complex visualizations with CoDeSys HMI and the controlling via a mobile phone is done with the use of SSI scripts (more in the articles to follow).
